In Philadelphia, a permit is typically not required if you are replacing windows of the same size in the same location. However, if the home is a designated historic building or if you are changing the opening size, a permit is required, costing approximately $65 to $72 plus a $3 state surcharge.
Owners of historic Philadelphia properties should budget a 15% to 25% premium. This accounts for specialized labor and custom-made wood windows required to meet local historic commission guidelines, which can push per-window costs above $1,500.
Homeowners in Philadelphia can expect to recoup between 70% and 80% of their window replacement costs upon resale. Energy-efficient upgrades are particularly valued due to the city's extreme climate, potentially saving $125 to $340 annually on utility bills.
The off-season months of November through February typically offer the best pricing. Contractors often provide 'winter discounts' of 10% to 15% to fill their schedules during lower demand periods.
